Wastewater with high salinity brings many challenges to the traditional biochemical process. High salt concentration, high osmotic pressure, microbial cell dehydration caused by the separation of cell protoplasm; salt precipitation effect of dehydrogenase activity is reduced; high chloride ions have a toxic effect on bacteria; high salt concentration, the density of wastewater increases, the activated sludge is prone to uplift the loss of easily caused by the collapse of the system, which seriously affects the purification effect of the biochemical system and the stable operation.
Based on the problem, traditional biochemical technology with obvious cost advantages is difficult to apply in high-salt organic wastewater. High salt biochemical technology for electroplating wastewater, salt-resistant, salinophilic microbial populations after targeted screening, domestication can be efficiently dealt with lithium recycling wastewater, etc., to ensure the stability of the treatment effect, thereby reducing the wastewater tonnage of water treatment costs.
Mainly used for the degradation of biochemical organic matter in high salinity organic wastewater, applicable to lithium recovery, electroplating, petrochemical, and other industries.
Biochemical treatment efficiency is high. Under the same water quality conditions, the operating cost of biochemical treatment is within 20% of the operating cost of adsorption, oxidation, and other processes.
